Detailed Description

data object that represents a "selection" in VTK.

vtkSelection is a data object that represents a selection definition. It is used to define the elements that are selected. The criteria of the selection is defined using one or more vtkSelectionNode instances. Parameters of the vtkSelectionNode define what kind of elements are being selected (vtkSelectionNode::GetFieldType), how the selection criteria is defined (vtkSelectionNode::GetContentType), etc.

Filters like vtkExtractSelection, vtkExtractDataArraysOverTime can be used to extract the selected elements from a dataset.

Combining Selections

When a vtkSelection contains multiple vtkSelectionNode instances, the selection defined is a union of all the elements identified by each of the nodes.

Optionally, one can use vtkSelection::SetExpression to define a boolean expression to build arbitrarily complex combinations. The expression can be defined using names assigned to the selection nodes when the nodes are added to vtkSelection (either explicitly or automatically).

static vtkTypeBool vtkSelection::IsTypeOf ( const char *  type)
static
virtual vtkTypeBool vtkSelection::IsA ( const char *  name)

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataObject.

vtkSelection* vtkSelection::NewInstance ( ) const
void vtkSelection::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkDataObject.

static vtkSelection* vtkSelection::New ( )
static
void vtkSelection::Initialize ( )
overridevirtual

Restore data object to initial state,.

Reimplemented from vtkDataObject.

int vtkSelection::GetDataObjectType ( )
inlineoverridevirtual

Returns VTK_SELECTION enumeration value.

Reimplemented from vtkDataObject.

Definition at line 78 of file vtkSelection.h.

unsigned int vtkSelection::GetNumberOfNodes ( ) const

Returns the number of nodes in this selection.

Each node contains information about part of the selection.

virtual vtkSelectionNode* vtkSelection::GetNode ( unsigned int  idx) const
virtual

Returns a node given it's index.

Performs bound checking and will return nullptr if out-of-bounds.

virtual vtkSelectionNode* vtkSelection::GetNode ( const std::string &  name) const
virtual

Returns a node with the given name, if present, else nullptr is returned.

virtual std::string vtkSelection::AddNode ( vtkSelectionNode )
virtual

Adds a selection node.

Assigns the node a unique name and returns that name. This API is primarily provided for backwards compatibility and SetNode is the preferred method.

virtual void vtkSelection::SetNode ( const std::string &  name,
vtkSelectionNode  
)
virtual

Adds a vtkSelectionNode and assigns it the specified name.

The name must be a non-empty string. If an item with the same name has already been added, it will be removed.

virtual std::string vtkSelection::GetNodeNameAtIndex ( unsigned int  idx) const
virtual

Returns the name for a node at the given index.

virtual void vtkSelection::RemoveNode ( unsigned int  idx)
virtual

Removes a selection node.

virtual void vtkSelection::RemoveNode ( const std::string &  name)
virtual

Removes a selection node.

virtual void vtkSelection::RemoveNode ( vtkSelectionNode )
virtual

Removes a selection node.

virtual void vtkSelection::RemoveAllNodes ( )
virtual

Removes all selection nodes.

virtual void vtkSelection::SetExpression ( std::string  )
virtual

Get/Set the expression that defines the boolean expression to combine the selection nodes.

Expression consists of node name identifiers, | for boolean-or, '&' for boolean and, '!' for boolean not, and parenthesis ( and ). If the expression consists of a node name identifier that is not assigned any vtkSelectionNode (using SetNode) then it is evaluates to false.

SetExpression does not validate the expression. It will be validated in Evaluate call.

virtual std::string vtkSelection::GetExpression ( )
virtual

Get/Set the expression that defines the boolean expression to combine the selection nodes.

Expression consists of node name identifiers, | for boolean-or, '&' for boolean and, '!' for boolean not, and parenthesis ( and ). If the expression consists of a node name identifier that is not assigned any vtkSelectionNode (using SetNode) then it is evaluates to false.

SetExpression does not validate the expression. It will be validated in Evaluate call.

void vtkSelection::DeepCopy ( vtkDataObject src)
overridevirtual

Copy selection nodes of the input.

Reimplemented from vtkDataObject.

void vtkSelection::ShallowCopy ( vtkDataObject src)
overridevirtual

Copy selection nodes of the input.

This is a shallow copy: selection lists and pointers in the properties are passed by reference.

Reimplemented from vtkDataObject.

virtual void vtkSelection::Union ( vtkSelection selection)
virtual

Union this selection with the specified selection.

Attempts to reuse selection nodes in this selection if properties match exactly. Otherwise, creates new selection nodes.

virtual void vtkSelection::Union ( vtkSelectionNode node)
virtual

Union this selection with the specified selection node.

Attempts to reuse a selection node in this selection if properties match exactly. Otherwise, creates a new selection node.

virtual void vtkSelection::Subtract ( vtkSelection selection)
virtual

Remove the nodes from the specified selection from this selection.

Assumes that selection node internal arrays are vtkIdTypeArrays.

virtual void vtkSelection::Subtract ( vtkSelectionNode node)
virtual

Remove the nodes from the specified selection from this selection.

Assumes that selection node internal arrays are vtkIdTypeArrays.

vtkMTimeType vtkSelection::GetMTime ( )

Return the MTime taking into account changes to the properties.

Reimplemented from vtkDataObject.

virtual void vtkSelection::Dump ( )
virtual

Dumps the contents of the selection, giving basic information only.

virtual void vtkSelection::Dump ( ostream &  os)
virtual

Dumps the contents of the selection, giving basic information only.

static vtkSelection* vtkSelection::GetData ( vtkInformation info)
static

Retrieve a vtkSelection stored inside an invormation object.

static vtkSelection* vtkSelection::GetData ( vtkInformationVector v,
int  i = 0 
)
static

Retrieve a vtkSelection stored inside an invormation object.

vtkSmartPointer<vtkSignedCharArray> vtkSelection::Evaluate ( vtkSignedCharArray *const *  values,
unsigned int  num_values 
) const

Evaluates the expression for each element in the values.

The order matches the order of the selection nodes. If not expression is set or if it's an empty string, then an expression that simply combines all selection nodes in an binary-or is assumed.

template<typename MapType >
vtkSmartPointer< vtkSignedCharArray > vtkSelection::Evaluate ( const MapType &  values_map) const
inline

Convenience method to pass a map of vtkSignedCharArray ptrs (or vtkSmartPointers).
